The phone, called Digno Rafre, will be available from mobile carrier KDDI next week for about ¥57,000 ($460). Bar soap shouldn’t be used to clean the device, a spokeswoman at Kyocera said, but foam soap can be used all over.

The Digno Rafre was developed to help people clean their smartphones thoroughly, given their presence in many different environments, such as outdoors and while cooking, the company said. Soap-proof devices were considered more difficult to manufacture than water-proof smartphones, but the company said it developed better sealing for the product.

Kyocera doesn’t have plans to market the Digno Rafre overseas.

Smartphones are not as clean as they might appear, due to their bacteria-loving warmth and contact with the hands and use near the mouth and nose. A Wall Street Journal report in 2012 found abnormally high number of bacteria indicating fecal contamination on all eight randomly selected phones.
